if statement with empty query

[Brad Tilton]

I don't have a strong javascript background and was wondering if someone could answer this question. I want to write an if statement that does something based on whether my query returned anything or not.

var gr = new GlideRecord('sc_cat_item');
gr.addQuery('u_software', current.sys_id);
gr.query();

if (gr didn't return a record)
dothis();
else
dothat();

How do I need to write the if statement or add to the query?

Thanks,
Brad

Try:

if (gr.hasNext()) {
  dothis(); // software found
} else {
  dothat(); // didn't find it
}

You can also try gr.getRowCount() with similar results, or while (gr.next()) for multiple.

That works great, thanks!
